Construction method for replacing construction waste backfilling with residue soil solidification of empty pile section of rotary excavating pile
The invention relates to the technical field of construction of an empty pile section of a rotary excavating pile, and discloses a construction method for replacing construction waste backfill by residue soil solidification of the empty pile section of the rotary excavating pile, which comprises the following construction steps of: forming a pile hole at a construction position through rotary excavating, sequentially soaking and screening earthwork excavated from the pile hole to form screened slurry, and forming the screened slurry into the pile hole; placing the screened slurry in a slurry pool; an empty pile section is formed in the upper portion of the pile hole, empty pile slurry is contained in the empty pile section, the empty pile slurry in the upper portion of the empty pile section is pumped out and placed in a slurry pool, and the empty pile slurry and the screening slurry are mixed to form solidified slurry; the hollow pile slurry in the lower part of the hollow pile section forms precipitated slurry; adding a curing agent into the slurry pool, and stirring and mixing to form cured slurry; and the hollow pile section is filled with the solidified slurry, the solidified slurry and the sediment slurry are stirred and mixed to form solidified soil, and after the solidified soil is solidified, the solidified pile filled in the hollow pile section is formed. In this way, the empty pile section is backfilled, and the effects of energy conservation, environmental protection, money saving and material saving are achieved in the mode of treating waste with waste.
本发明涉及旋挖桩空桩段施工的技术领域，公开了旋挖桩空桩段渣土固化代替建筑垃圾回填的施工方法，包括以下施工步骤：在施工位通过旋挖成型桩孔，将桩孔开挖出来的土方依序经过泡浆、筛分后，形成筛分泥浆，将筛分泥浆置于泥浆池中；桩孔的上部形成空桩段，空桩段中具有空桩泥浆，将空桩段上部中的空桩泥浆抽出，置于泥浆池中，空桩泥浆与筛分泥浆混合，形成固化泥浆；空桩段下部中的空桩泥浆形成沉淀泥浆；在泥浆池中加入固化剂，搅拌混合形成固化浆；将固化浆填充至空桩段中，且将固化浆与沉淀泥浆搅拌混合，形成固化土，固化土固化后形成填充在空桩段中的固化桩。这样，使空桩段得到回填，通过以废治废的方式、达到节能环保、省钱省料的效果。
